TO ALL WHOM IT MAY' CONCERN:

Be it known that I, SAMUEL HALL, of the city, county, and State of New York, have invented, made, and applied to use a new and useful Machine for Bending Tire and Fifth-Wheel Plates; and I do declare the following to be a. full, clear, and correct description ot' my invention, reference being made to the accompanying drawings, making part oi` this specification, and to the letters of reference marked thereon, in which- Figure 1 is an end'view of my improved machine.

Figure 2, afront sectional view of `the same.

Figures 3, 4, and 5 are views of parts used in connection with the machine in bending"fth-wheel plates.

In `the drawings, like parts of the invention are indicated by the same letters offreference.

The nature of my invention consists in the construction and operation of an improved machine for the purpose of bending tire and iiftliwhcel" plates, as more fully hereinafter described.

To enable those skilled in the arts to make and use my invention, I will proceed to describe'the same.

A is a bed-piece for supporting the operating parts of my improved machine. B B shows the box frame of the machine, which` frame may be bolted to the bed-piece A, or may be cast with the same. C shows the roller box placed within the frame B B. Within this box C are thejournal boxes D D for holding the upper or top bending roller forbending the tire or ifth-wheel plates. Directly above this roller box, and bearing upon the upper side of the same, are the lifting or adjusting screws F, which are inserted through the cover of the box frame B B. G G show projections on the top of the roller box C, which projections receive and retain the screws` F, the projections being provided with a slot on one side to receive a lifting key, which is slotted to pass through the groove of the screws, so that as the screws are withdrawn the boxC shall be lifted with them.

These screws are provided with the pinions H gearing into the intermediate pinion I, of the same diameter asA the-pinions II. This intermediate pinion I is supported upon the stud J, substantially held in the cover of the box frame B B, or a third lifting screw may be used in its stead. This, intermediate is provided with the hub K to receive the crank L. M shows the roller-shaft carrying the bending roller E. p This Shaft passes through the end of the boxframe B B a-nd the arm N, which arm, N, is attached to the roller box C above and below the shaft M. Upon this shaft is keyed the spur-Wheel O, gearing into the pinions l? and P2, one of which, P, i is held upon a stud inserted in the upper end of the arm N, and the other, P2, upon the shaft Q, running under the bed-plate A and supported 'by the box frame B. S S' show braces, the one curved and the other diagonal, placed on the box frame B B at each side to strengthen that portion of the frame B B below which the iron to be bent passes. T show columns to receive the screws or bolts holding the cover tothe box frame B B. Upon the shaft Q is placed a connection, U, provided with a stud, V, which stud,.V, ivhen the machine is in operation, is inserted in a slotted opening in the front end ofthe box frame B B, and enters an opening in the front end of the roller box C, thus serving to raise or lower the shaft Q and retain it on a line with the pinion, (132,) end. W show recessed ribs upon the bed-plate A, which recessed ribs receive the lower rollers X, over which thev iron to be bent passes. At the bottom of the box frame B B are the projections a to receive and retain the movable supporting arm I), attached to the bed-plate A in any convenient manner. i

The machine being thus constructed, the operation is as follows: The rollers X are placed Within the recesses W, in accordance with the diameter of the tire to be formed. The iron to be bent is then introduced into the machine, and the roller E is adjusted to the same by means of the screws F'operated by the gearing H, I,- and H and crank L, which screws bear upon and are attached to the upper side of the roller box G. Mption being now imparted and communicated to the machine through the pinionsl? and P and spur-wheel O, the iron is drawn through the machine by the pressure of the roller E upon the iron placed `upon the rollersX, and the operation just described is repeated until a perfect tire is formed. When the tire has been formed, to remove the same from the machine the arm b isreleased from the frame and away from the rollers X," and the pin V is removed from the opening in the box frame and the rod U, theupper roller E is relievedV from pressing upon the tire by means of the adjusting screws, and the tire can be readilywithdrawn from the rollers X. The tire having been removed from the machine and the parts just released having been restored to the position they usually occupy, a second bar of iron may be inserted in the machine and the operation just described beirepeated. The arms l) are only used 'when the heavier kinds of iron are employed. When it is desired to bend whatis known as a fifth-wheel tire or-plate the iron is inserted cdgewisc uponv the rollers X, placed as previously according to the diameter' required. Inasmueh as Amore power isr/equired in this operation than in the previous one, and in order that the roller E may not crook the bar while .passingur through the machine, -I employ two sliding boxes, c c, one sliding within the back part of the box frame B B, and the other in a dove-tailed slot in the bed-plate A. These' sliding boxes are provided with the vertical rollers e e, which bear lupon vthe sides of the iron and keep the same perfectly flat and with the seniieircular recess g to receive the upper roller E, if required. One of thesesliding boxes is adjusted by means of a taper key, and the other -is adjusted by means of a thumbscrew, z., passing` through a block, z, bearing against the lugs jj.

The peculiar advantages resulting from the use of amachinc constructed as described are, that the pressing or bending roller and its journal boxes are held in a'sliding box working withinl the box frame, thus-adding great strength to the machine and decreasing thcliabilityr of the same to frequently break or get out of order. Again, the tire when formed can be more readily and expeditiously removed from lthe machine than in the ordinary tire machine, in which the tire is removed by springing it apart, so that it can pass over the pressing or bending roller, which operation is an exceedingly laborious one; and iinallyin thatthc adjusting screws are' connected to the roller box, as shown, and operate the bendin.;r roller-by means of gearing, thus adjusting it much more evenly than where the screws'bear upon the `journal box only and are not adjusted by means of gearing.

While in the present instance I havo shown the arm N in a vertical position, I do not intend to confine myself to this position ofthe same, as I am aware that the same may be placed at right angles to the machine, if desired, which in some cases might prove of advantage.`

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. I claim the box frame B, B, constructed substantially as shown for the purpose set forth.

2. In combination with the bending roller, held and adjusted substantially as described, I claim the rollers 4X, when the saine shall be combined, constructed, and operated substantially as shown for the purposes set forth.

In combination withl the same, the use ofthe sliding boxes, constructed as shown for the'purposes specified.

SAMUEL HALL.
